Mercurial subppos at current revision of a specific branch

Question

I am completely new to mercurial, I read a lot of topics on this topic, but I still can’t understand if I can achieve what I am trying to do.

In principle, it would be interesting for me to clone the current revision of the branch from the main repository and its sub-position in one command (acting on the main repo). I will try to explain this in a minute.

Let's say that I split my code into modules (only one module in the example below). I would like to have each module in my own repository and master repo (the one that has .hgsub) as glue to keep all the back-ups in place. The master repo simply contains .hgsub and a script, which are (1) hg archiveeach sub-directory in a predefined directory, and (2) performs non-root code building. All development, commits, push, pull, merge are performed in a separate subposition.

# create a module (subrepo of the master)
hg init subrepo
cd subrepo/
echo "a file" > aFile.c
echo "another file" > anotherFile.txt
hg add
hg ci -m "initial rev of subrepo"

# create the main (master) repo & add the reference to subrepo
cd ../
hg init main
cd main
hg clone ../subrepo subrepo
echo subrepo = ../subrepo > .hgsub
echo hg archive and out-of-source build > build.script
hg add
hg ci -m "initial rev of main repo"

So far so good. If I hg clone main, I get the current revision of the default subrepo branch, as expected.

BUT, imagine that I am ready to send my code to release: 1.0.0. I would do the following.

# create the branch 1.0 to manage the bug fixes to 1.0.0 and furthers
cd ../subrepo/
hg branch 1.0
hg ci -m "creating the branch 1.0"

# backstep to the main line to carry on the development of new features
hg up default 
echo "working in the main line" > aNewFeature.c
hg add
hg ci -m "carrying on the development in the main line (a new feature)"
hg glog
